SideHero — AI life coaching for iOS and Android.
Last updated: 24 August 2026 · Effective: 24 August 2026
This Privacy Policy explains what information the SideHero mobile app (“SideHero”, “the app”) collects, why we collect it, who we share it with, and the choices you have. It applies to the SideHero apps for iOS and Android and to our website. SideHero is provided by App Dev Contracting Ltd (“we”, “us”), the data controller for the purposes of this policy.
If you have any questions, contact us at support@sidehero.ai.
To create an account you provide an email address and a password. Where the option is offered, you can instead sign in with Google; the sign-in methods available to you vary by platform and app version. Authentication is handled on our behalf by Clerk, Inc. When you sign in with Google, Google shares your email address, basic profile information and profile image with us. We never see or store your Google password.
SideHero works by turning what you tell it into a plan, so the content you enter is central to the service. This includes:
This content is stored on your device. It is also transmitted to AI model providers when needed to generate a response or plan (see AI processing).
Please don't share sensitive details you would not want processed by an AI service. Because coaching conversations are open-ended, you may choose to mention health, financial or other personal matters. We ask that you avoid including information you consider sensitive, and never include payment card details, passwords or government identifiers in chat.
Subscriptions are sold through the app store you installed SideHero from — Apple on iOS or Google Play on Android — and are managed on our side with RevenueCat. We receive your subscription status, the product purchased, and purchase and renewal dates, linked to your account identifier. We never receive your credit card or payment details — payment is handled entirely by Apple or Google under their own privacy policies.
We use PostHog (hosted in the European Union) to understand how the app is used and where people get stuck. This covers which features you use and when, your account identifier, and basic device and app information such as device model, operating system version and app version. The contents of your chats and objectives are not sent to our analytics provider — only that an event happened.
We also use PostHog (hosted in the European Union) on our marketing website. This is a separate analytics project from the app, and visitors to the website are not identified — no account is involved and no profile is created for you. We record pages viewed, the page you arrived from, approximate location derived from your IP address (country and region, not a precise location), browser and device type, and clicks on page elements. This processing relies on our legitimate interest in understanding and improving our website; you can opt out entirely by enabling your browser's Do Not Track setting or by using an ad/tracking blocker.
We use Sentry (hosted in the European Union) to capture crashes and errors so we can fix them. Reports include the error, the part of the app you were in, app and device information, and your account identifier. We do not attach your chat content or objective text to error reports.
With your permission, SideHero sends notifications at the times you schedule for your habits, reminders and newsletters. These are generated on your device rather than sent from our servers, so we do not collect or store a push token for your device. You can turn notifications off at any time in your device Settings; the rest of the app continues to work.
Where the GDPR or similar laws apply, we rely on: performance of a contract for providing the app and its core features; legitimate interests for security, abuse prevention and product analytics; consent for device notifications; and legal obligation where we must retain records.
To generate plans, newsletters and coaching replies, the relevant parts of your conversation and objectives are sent from the app to our own backend servers, which forward them to third-party large language model providers acting as our processors. Depending on the model configured at the time, these providers may include Google (Gemini), xAI (Grok) and/or OpenAI.
We instruct our model providers not to use your content to train their models, and their retention is limited to what is needed for abuse monitoring under their own terms.
The coach may also call optional tools on your behalf, such as a public weather service (Open-Meteo) and, where enabled, a web search service. Only the query needed for the tool call — for example a city name or a search phrase — is sent to those services.
AI-generated coaching content is for general motivational and organisational purposes only. It is not medical, psychological, legal or financial advice, and it can be inaccurate. Please use your own judgement.
We do not sell your personal data and we do not share it with third parties for their own marketing. We share data only with the service providers below, and only as needed to run SideHero:
| Provider | Purpose | Data involved |
|---|---|---|
| Clerk | Authentication and account management | Email address, sign-in credentials, Google profile basics |
| Apple | Subscription payments on iOS | Purchase and subscription records (payment details stay with Apple) |
| Google Play | Subscription payments on Android | Purchase and subscription records (payment details stay with Google) |
| RevenueCat | Subscription state and entitlements | Account identifier, subscription status and history |
| Google (Gemini), xAI (Grok), OpenAI | AI generation of plans and replies | Chat and objective content sent for processing |
| Open-Meteo, web search (when enabled) | Optional coach tools | The specific query, e.g. a place name |
| PostHog (EU) | Product analytics | Usage events, counters, account identifier, device/app info |
| PostHog (EU) | Website analytics | Pages viewed, referrer, approximate location from IP, browser/device type (no account identifier) |
| Sentry (EU) | Crash and error reporting | Error data, app/device info, account identifier |
| Our hosting providers | Running our service | Account records and subscription state |
We may also disclose information if required by law, to enforce our terms, to protect the rights and safety of our users or the public, or in connection with a merger, acquisition or sale of assets (in which case we will notify you before your data becomes subject to a different policy).
We are based in the United Kingdom, and our providers operate in the United States, the European Union and other countries. This means your information may be transferred to and processed outside your country of residence. Where we transfer personal data out of the UK/EEA, we rely on appropriate safeguards such as the European Commission's Standard Contractual Clauses.
Depending on where you live, you may have the right to access, correct, delete, or receive a copy of your personal data, to object to or restrict certain processing, and to withdraw consent. To exercise any of these rights, email support@sidehero.ai. We will respond within the timeframe required by applicable law (usually 30 days). You may also lodge a complaint with your local data protection authority.
In-app controls: you can delete individual objectives and conversations at any time, sign out from Settings, and turn notifications off in your device's Settings. You manage or cancel your subscription where you bought it — in Settings › Apple Account › Subscriptions on iOS, or in the Google Play Store on Android.
You can request full deletion of your SideHero account and its associated data via the app using the "Delete Account" button in the settings screen or by emailing support@sidehero.ai from the address on your account. Deletion removes your account record, objectives and conversations held on our systems. Uninstalling the app removes the data stored on your device. Note that cancelling a subscription is done through the App Store (iOS) or Google Play (Android) and is separate from deleting your account — deleting your account does not automatically cancel or refund an active subscription.
All traffic between the app and our services is encrypted in transit. Access to our systems is restricted, and data held on your device is protected by your operating system's built-in app protections. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.
SideHero is not directed to children and is not intended for anyone under 13 (or the minimum age of digital consent in your country, if higher). We do not knowingly collect personal data from children. If you believe a child has provided us with personal data, contact us and we will delete it.
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page, and for material changes we will provide a more prominent notice in the app or by email. Continuing to use SideHero after an update means you accept the revised policy.
